Description

Technical Field

[0001] This utility model relates to the field of cable gripping technology, and in particular to a rotatable and adjustable cable gripping device for mine safety. Background Technology

[0002] Serious safety hazards exist in mining and underground operations. When miners are working at heights or climbing, the risk of falling is fatal. Traditional safety harnesses and slings are unreliable. Current technology typically uses safety harnesses to ensure miners' safety at heights. The safety harness connects the miner to the sling, which is then secured to the safety rope by friction or a simple locking mechanism. However, traditional slings may not be easy to rotate or adjust. Once installed, their position is relatively fixed, and their clamping force is limited. Under significant external force or vibration, the wire rope is prone to slippage, posing a safety hazard.

[0003] Therefore, those skilled in the art have provided a rotatable adjustable gripper for mine safety to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotatable and adjustable cable gripper for mine safety. Pulling the limiting block moves the insert rod forward, away from the protrusion, and pushes the protrusion into the cavity. At this time, rotating the rotating column can drive the lower device to rotate. When fixation is required, the protrusion is pushed out and engages with the rotating block. Releasing the limiting block resets the insert rod and engages with the protrusion, keeping the device stable and preventing it from rotating on its own due to external forces.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotatable and adjustable safety gripper for mining includes a fixed plate and a mounting column. A rotating mechanism is provided in the middle of the lower end of the fixed plate, and two clamping mechanisms are provided on one side of the upper end of the fixed plate. The rotating mechanism includes a rotating column, the upper end of which is rotatably connected to the middle of the inner wall of the fixed plate. A rotating block is fixedly connected to the upper end of the outer wall of the rotating column. A cavity is formed in the middle of the inner wall of the lower end of the fixed plate. A first return spring is fixedly connected to the top surface of the cavity. A protrusion is fixedly connected to the lower end of the first return spring. A second return spring is fixedly connected to the front end of the inner wall of the cavity. A plug rod is slidably fixedly connected to the second return spring. A limit block is fixedly connected to the middle of the lower end of the plug rod. Two connecting grooves are formed in the lower part of the front end of the rotating column.

[0007] The above technical solution involves pulling the limiting block to move its insertion rod forward away from the protrusion, then pushing the protrusion into the cavity, rotating the rotating column, and thus driving the lower device to rotate. When the device reaches the desired position, the protrusion is pushed out and engages with the rotating block. The limiting block is then released, allowing the insertion rod to engage with the protrusion, ensuring stability during use and preventing the device from rotating on its own due to external forces.

[0008] Furthermore, two connecting blocks are fixedly connected to one side of the upper end of the fixed plate. Each of the two connecting blocks has a sliding groove at its upper end. Threaded rods are rotatably connected to both ends of the inner walls of the two sliding grooves. Threaded sleeves are fitted onto the outer walls of the two threaded rods. Sliding blocks are fixedly connected to the upper ends of the two threaded sleeves. Clamping blocks are fixedly connected to the upper ends of the two sliding blocks. Clamping blocks are fixedly connected to the ends of the upper ends of the two connecting blocks away from the center of the connecting blocks. Worm gears are fixedly connected to the ends of the outer walls of the two threaded rods away from the center of the connecting blocks. Worms are provided at the ends of the inner walls of the two connecting blocks away from the center of the connecting blocks.

[0009] With the above technical solution, rotating the worm gear causes the threaded rod to rotate, which in turn drives the threaded sleeve and sliding block to move. The locking block then moves inward, and the wire rope is placed on the upper end of the clamping block. Then, the worm wheel is rotated in the opposite direction, causing the locking block to move outward, clamping the wire rope between the clamping block and the locking block, preventing the wire rope from slipping out due to external force.

[0010] Furthermore, the lower end of the outer wall of the mounting column is provided with a threaded section, and a first nut is sleeved on the outer wall of the threaded section. Two external threaded slotted pins are evenly provided at the front end of the inner wall of the mounting column, and a second nut is provided at the rear end of each of the two external threaded slotted pins.

[0011] Through the above technical solution, the engagement of the threaded section and the first nut ensures that a stable threaded connection can be formed between other connecting parts of the mounting post. The external thread slotted pin and the second nut facilitate the connection or separation of the mounting post from other parts.

[0012] Furthermore, the protrusion engages with the rotating block;

[0013] The above technical solutions increase the overall structural strength of the device.

[0014] Furthermore, the limiting block slides on the inner wall of the cavity, and the rear end of the insertion rod passes through the protrusion to the outside of the protrusion;

[0015] The above technical solutions reduce the overall structure's volume and space occupation.

[0016] Furthermore, both of the aforementioned worm gears mesh with the worm.

[0017] Through the above technical solution, the worm gear has a self-locking function to prevent the threaded rod from rotating on its own.

[0018] Furthermore, both of the sliding blocks slide on the inner wall of the groove;

[0019] Through the above technical solution, the chute has a guiding function, providing stable support for the sliding block, making its movement smoother and reducing vibration and shaking.

[0020] Furthermore, the rear ends of both externally threaded slotted connecting pins extend through the connecting groove to the outside of the connecting groove;

[0021] The above technical solution can effectively and firmly connect the two components together, enhancing the strength and stability of the connection.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a rotatable and adjustable cable gripper for mine safety. Pulling the limiting block moves its insert rod forward away from the protrusion. Then, the protrusion is pushed into the cavity. Rotating the rotating column drives the lower device to rotate. When it rotates to the desired position, the protrusion is pushed out and engages with the rotating block. The limiting block is released, and its insert rod engages with the protrusion, keeping it stable during use and preventing the device from rotating on its own due to external forces.

[0024] 2. This utility model proposes a rotatable adjustable wire rope gripper for mine safety. When the worm gear is rotated, the threaded rod rotates accordingly, which in turn drives the threaded sleeve and sliding block to move. The locking block moves inward accordingly, and then the wire rope is placed on the upper end of the clamping block. Then, the worm gear is rotated in the opposite direction, causing the locking block to move outward, clamping the wire rope between the clamping block and the locking block, preventing the wire rope from slipping out due to external force, and ensuring the safety of operation.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides a specific embodiment of a mine safety rotatable adjustable gripper, comprising a fixed plate 3 and a mounting column 4. A rotating mechanism 1 is provided in the middle of the lower end of the fixed plate 3, and two clamping mechanisms 2 are provided on one side of the upper end of the fixed plate 3. The rotating mechanism 1 includes a rotating column 101, the upper end of which is rotatably connected to the middle of the inner wall of the fixed plate 3. A rotating block 102 is fixedly connected to the upper end of the outer wall of the rotating column 101. A cavity 103 is opened in the middle of the inner wall of the lower end of the fixed plate 3. A first return spring 104 is fixedly connected to the top surface of the cavity 103. A protrusion 105 is fixedly connected to the lower end of the first return spring 104. A second return spring 106 is fixedly connected to the front end of the inner wall of the cavity 103. An insert rod 107 is slidably fixedly connected to the second return spring 106. A limit block 108 is fixedly connected to the middle of the lower end of the insert rod 107. Two connecting grooves 109 are opened in the lower part of the front end of the rotating column 101.

[0038] Pull the limiting block 108 to move its insertion rod 107 forward away from the protrusion 105. Then push the protrusion 105 into the cavity 103. Rotate the rotating column 101 to drive the lower device to rotate. When it rotates to the desired position, push the protrusion 105 out and engage it with the rotating block 102. Release the limiting block 108 so that its insertion rod 107 engages with the protrusion 105, so that it remains stable during use and prevents the device from rotating on its own due to external force.

[0039] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7Two connecting blocks 201 are fixedly connected to one side of the upper end of the fixed plate 3. Each connecting block 201 has a groove 202 at its upper end. Threaded rods 203 are rotatably connected to both ends of the inner walls of the two grooves 202. Threaded sleeves 204 are fitted onto the outer walls of the two threaded rods 203. Sliding blocks 205 are fixedly connected to the upper ends of the two threaded sleeves 204. Locking blocks 206 are fixedly connected to the upper ends of the two sliding blocks 205. Clamping blocks 207 are fixedly connected to the upper ends of the two connecting blocks 201 away from their centers. Worm gears 208 are fixedly connected to the outer walls of the two threaded rods 203 away from their centers. Worm gears 208 are fixedly connected to the inner walls of the two connecting blocks 201 away from their centers. One end of each component is provided with a worm gear 209. When the worm gear 209 is rotated, the threaded rod 203 rotates accordingly, which in turn drives the threaded sleeve 204 and the sliding block 205 to move. The locking block 206 moves inward accordingly. Then, the wire rope is placed on the upper end of the clamping block 207. Then, the worm wheel 208 is rotated in the opposite direction, causing the locking block 206 to move outward, clamping the wire rope between the clamping block 207 and the locking block 206, preventing the wire rope from slipping out due to external force. The lower end of the outer wall of the mounting column 4 is provided with a threaded section 5. The outer wall of the threaded section 5 is fitted with a first nut 6. The front end of the inner wall of the mounting column 4 is evenly provided with two external threaded slotted pins 7. The rear ends of the two external threaded slotted pins 7 are provided with second nuts 8.

[0040] The engagement of threaded section 5 and first nut 6 ensures a stable threaded connection between the mounting post 4 and other connecting components. The external threaded slotted pin 7 and second nut 8 facilitate the connection or separation of the mounting post 4 from other components. Protrusion 105 engages with rotating block 102, increasing the overall structural strength of the device. Limiting block 108 slides on the inner wall of cavity 103. The rear end of insertion rod 107 passes through protrusion 105 to the outside of protrusion 105, reducing the overall volume and space occupied. Both worm gears 208 mesh with worm 209, which have a self-locking function to prevent threaded rod 203 from rotating on its own. Both sliding blocks 205 slide on the inner wall of groove 202, which has a guiding function, providing stable support for the sliding blocks 205, making their movement smoother and reducing vibration and sway. The rear ends of both external threaded slotted pins 7 pass through connecting groove 109 to the outside of connecting groove 109, effectively and firmly connecting the two components together, enhancing the strength and stability of the connection.

[0041] Working principle: When the user rotates the worm gear 209 clockwise, the threaded rod 203 also rotates. The threaded sleeve 204 moves along the axis of the threaded rod 203, thereby driving the sliding block 205 and the locking block 206 to move inward, making room for the placement of the wire rope. At this time, the operator places the wire rope on the upper end of the clamping block 207. The user then rotates the worm wheel 208 counterclockwise, thereby driving the locking block 206 to move outward, clamping the wire rope between the clamping block 207 and the locking block 206, preventing the wire rope from slipping out due to external force. The user pulls the limiting block 108, causing its insertion rod 107 to move forward, away from the protrusion. Block 105, then the operator pushes the protrusion 105 into the cavity 103. The user rotates the rotating column 101, which in turn drives the lower device to rotate. When the device rotates to the required position, the protrusion 105 is pushed out and engages with the rotating block 102. The limiting block 108 is released so that the insertion rod 107 engages with the protrusion 105, so that it remains stable during use and prevents the device from rotating on its own due to external force. The mounting post 4 is placed inside the rotating column 101. Then the external threaded slotted pin 7 passes through the rotating column 101 and the mounting post 4, and then it is fixed by the second nut 8, so that its lower end rotates and is fixed to the rotating column 101.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
